Re: Java 7 and Hadoop
We should officially support it in Hadoop (one piece of BIGTOP-458
which is for supporting it across the whole stack).
Now that HADOOP-8370 (fixes native compilation) is in the full tarball
should work. A good next step would be updating JAVA_HOME on one of
the Hadoop jenkins jobs to use jdk7.
